Plastic components are often fixed with the aid of adhesives to prevent them from slipping during further process handling. Acrylate-based adhesives in particular usually adhere very well to many plastics. They have a strengthening and supporting effect for load transfer and stress reduction. Acrylic adhesives, which are also used for permanent bonding, are characterised by short processing times and high strength to many plastics and elastomers. These adhesives achieve, for example, as 2-component adhesives on low-energy plastics such as PC, PMMA, PVC etc., good shear and peel strengths as well as good impact strength under dynamic loads. From the 3M Scotch-Weld series, even acrylic adhesives have been developed in the meantime, which provide good results on difficult to bond plastics with low surface energy without any surface preparation or primer.

Bonding can be achieved by applying chemicals such as epoxies and plastic agents that bond by evaporation of a solvent or by curing a bonding agent with heat, pressure or time. Foams are quite common in everyday life: They are used in everything from upholstery and mattresses to insulation materials. They are based on a wide range of plastics as raw materials. However, not every adhesive is suitable for every material. In view of the wide range of variants, it can therefore be useful to always test how the adhesive behaves on small samples of the material beforehand. Further information. The cold-crosslinking HTV silicone rubbers are plastically deformable materials which are used, for example, as cable sheathing, for electrical insulation or for sealing and damping purposes.To use Super Steel Epoxy make sure the surfaces to be bonded are clean and dry and free from oil, dirt or grease.

Thermosets are plastics which are closely networked during processing. This cross-linking takes place chemically between the molecules of the starting materials. The process is no longer reversible. Once such a material has cross-linked, it can only be processed mechanically. Duroplastics are usually hard and brittle. ABS (acrylonitrile-butadiene-styrene copolymer) is today an everyday plastic which is widely used because of its surface hardness, high impact resistance and good resistance to weathering, ageing and chemicals: For example, for sanitary pipes or housings of household and electrical appliances as well as for toys, plates and foils.

Rubber or rubber-like materials are widely used in industry and everyday life: for example in seals and rollers, in vibration dampers or for footwear. In general, a whole range of different types of adhesives are suitable for bonding rubber. However, the optimum adhesive always depends heavily on the rubber compound and the intended use. Further information. Silicones, with their low-energy, extremely repellent surfaces, are considered to be difficult or almost impossible to bond. Among the few adhesive products that show usable results here are, for example, new types of silicone transfer adhesives that, in combination with adhesive tapes, even enable efficient automation of series production processes - for example in the automotive sector. Further information. It hardens in 5 minutes and cures in 10 minutes. It works well under a maximum temperature of 315°C (<100 continuous). It contains 54g/l solvent. It is not suitable for soft plastic and polypropylene.Apply the resin to both surfaces to be joined and clamp or tape the parts together until Super Steel has set hard.

immediately (working time is approximately 5 min.). Remove any excess Plastic Weld immediately. 7. CURE With this information, the adhesive and surface treatment can be selected based on technical data sheets, experience and the literature. If it is important, adhesive samples should be made and tested before the adhesives are used. In mechanical testing, the bonded joint is loaded until it breaks. The type of fracture provides information about the quality of the bond and indicates where defects occurred during bonding. An adhesion fracture is when the adhesive detaches from the joined part. A cohesion fracture is a fracture in the adhesive itself and a fracture in the part to be joined describes a fracture outside the adhesive surface in the part to be joined. The bonding and gluing of plastics is very common in a wide range of industrial processes and products. PET (polyethylene terephthalate) is known as a glass substitute in beverage bottles, in filling fibres and as fibres for clothing. In electrical engineering, PET films are used as carrier material for magnetic tapes. PET has high stiffness, hardness, abrasion resistance and is resistant to diluted acids, oils, fats and alcohols. However, it is sensitive to hot steam.PMMA - polymethyl methacrylate, also known as Plexiglas and acrylic glass, impresses with its optical and surface properties. In everyday life, corrugated sheets, for example for the roofing of garden arbours or pergolas, are often mistakenly offered as plexiglass. In reality, they are made of polycarbonate or PVC, which can make a big difference when bonding the material. The same applies to so-called hobby glass from the DIY store. For bonding on low-energy plastics such as PMMA, the surface energy is of central importance. However, caution is advised when using certain solvents for bonding preparation. Otherwise, there is a wide range of high-performance adhesives on the market for efficiently bonding PMMA to numerous other materials. Further information. POM (polyoxymethylene) is one of the most commonly used thermoplastics worldwide. It's valued for its high impact resistance, strength, hardness and rigidity. Due to its low coefficient of friction, high heat deformation resistance, excellent sliding and abrasion behaviour in combination with low coefficients of friction, the material is often used as an engineering plastic - primarily for precision parts such as gears, shafts, switch gears, etc. The high recovery elasticity of polyoxymethylene makes the plastic useful for applications in the field of snap-fit connections. evenly colored. 6. APPLICATION: Apply a small amount of mixture to both surfaces and assemble parts Mechanical pretreatment by brushing, grinding, sanding or sandblasting - this changes the roughness and the size of the surface area effective for the bond. At the same time, loosely adhering reaction products, polishing and sliding agents and stabilisers are removed.

In contrast, the low-viscosity, hot-crosslinked silicone rubber (RTV/NV) is medium-elastic, has good flowability and low viscosity. It is therefore particularly suitable for the manufacture of elastic wax or relief casting moulds, casting moulds for figures or decorative panels, moulds for casting with epoxy / casting resin, cement, plaster or other flowable materials. Bonds on some low-energy plastics such as polyolefins (PP, PE and PTFE) and silicone-containing joining partners are critical, however. High-energy (polar) surfaces offer the adhesive better adhesion than low-energy (non-polar) surfaces. EPDM (ethylene propylene diene rubber) is used for sealing profiles. In contrast to NBR, EPDM has very good electrical insulation properties, excellent resistance to ozone and sunlight, and outstanding resistance to ageing. Chemically bonds certain types of plastic coving or trunking. For use with solvent weld waste products. Can achieve up to 55 joints per tub. Supplied with brush applicator. Most foams are produced by means of foam extrusion: the heated plastic expands to 20 to 50 times its volume as it flows out of a perforated nozzle. Rotating knives then cut the resulting foam strands into closed-cell foam particles of a few millimetres in size, from which various products are formed.At the same time, it's possible to use adhesive techniques to integrate properties into the component that go beyond the actual joining, such as insulation resistance to electrical potentials, sealing against gases and liquids, damping of vibrations, protection against corrosion and compensation of different joining part dynamics. PA - polyamide is high-strength and impact-resistant. Its abrasion and wear resistance combined with excellent sliding properties make it a preferred construction material in machine or vehicle construction. Because of its high mechanical strength, it has now even displaced many metal components in vehicle construction - sometimes reinforced with carbon or glass fibres. But PA is not easy to bond. High bond strengths of PA materials require the use of special pre-treatment methods or specially developed, reactive adhesives. Further information.
